-# Allows attributes to be shared within an inheritance hierarchy, but where each descendant gets a copy of
-# their parents' attributes, instead of just a pointer to the same. This means that the child can add elements
-# to, for example, an array without those additions being shared with either their parent, siblings, or
-# children, which is unlike the regular class-level attributes that are shared across the entire hierarchy.
